前几天中了spyware，用spyout好不容易清除了，但ie却被劫持了，用3721修复后可以用了，但桌面背景却被锁住了，电脑启动速度也慢了很多。用兔子ie修复检测到有一个std software插件，却怎么也清除不了。再windows/system32目录下有个文件stdup.dll也删不掉。用 HijackThis 1.99.1生成的log是：

好心人帮忙看一下，咋办啊？急啊

开始→控制面板→性能和维护→管理工具→服务→查找StdService→右击→属性→启动类型→禁止→应用→停止→确定。

重新启动电脑, 开机检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式进入Windows

运行Hijackthis，扫描结束后在下列选项前打上勾，然后选修复“Fix Checked”：

O2 - BHO: std software - {6A512BF7-EC78-4e8d-9841-6C02E8FA9838} - C:\WINDOWS\SYSTEM32\stdup.dll
O23 - Service: Pigeon_Server (PigeonServer) - Unknown owner - C:\WINDOWS\Server.exe (file missing)

显示隐藏文件

双击我的电脑--工具---文件夹选项--查看选项卡--单击选取"显示隐藏文件或文件夹"--清除"隐藏受保护的操作系统文件（推荐）"复选框。在提示您确定更改时，单击“是”--单击“确定”。

然后找到如下文件并删除（如果有的话）。
C:\WINDOWS\SYSTEM32\stdup.dll
C:\WINDOWS\SYSTEM32\STDSVER.DLL

太感谢斑竹大哥了
